Toall whom, .it may concern:

a`,citizen.. of the United States, residing at Riverside, Iin thecounty of Riverside and State of California, have invented new and useful Improvements in Vehicle-Wheels, of -which .the'followin is a speciiication.

My invention reIates to pneumatic wheelrims, and is es ecially applicable to autocars, motor-eye es, and similar vehicles; and the object thereof is to, roduce a pneumatic wheel-rim of 'greatdura ility and which cannot be punctured.I I accom lish this object by the wheel-rim described erein and illustrated in the accompanying drawings, in which n Figure 1 is a side elevation, artl in central section, of a wheel equippc wit my improved rim.. Fig. 2 is `a section on the line 2 2 of Fig. 1. Flg. 3 is a ers ective view-of the rubber cushlon-blocs p aced between sections of the tire. Fig. 4 is an enlar ,ed detail of the turnbuckle attachment. lgig. 5 is an enlarged detail of the spring-tension atthereto in the usual manner.

tachment.

In the drawings, 5 is the ordina hub of the wheel, and 6 represents the spo es secured- On the outer ends of the spokes is the felly 7, in the outer ,edge of which is a channel or trough 8, which \is preferably semicircular. At suitable distances around the felly it is rovided4 with pins 9, which project into soc ets 10 in the sections 1l, composed of non-puncturable material. WoodIforms a good material for these sections, as it is light and strong.- Papier-rh\ ^ch is also a good material. These wood s ctions are of a similar curvature to v the felly and in the edge next to the felly con- -tain a semicircular trough, which, with the trough in the folly, forms the tire-receiving channel, in which 1s contained the pneumatic tube 12, which can be inflated and deflated throug valve 13 in the usual manner. There may be as many of these Wood sectionsas desired. vI have shown six, as inan ordinary autowheel that number provides a wood section which may be so cut as to retain the eatest strength of the wood; but there ma ge more or less of these sections,.if desire and the may be constructed of other material. T e ends of these wood sections are cut on a slant, as shown in Fig. 1, and are provided with recesses 14, in which are re- LWrLLrAM B. Snwrmaf ceived lugs 15 of the rubber' cushion-blocks 16, which are placed between the various sections of the wood sfctions to )ermit of the expansion and contraction of t e outer portion 'of the rimof the wheel when in use. These cushion-blocks are of elastic rubber and are therefore compressible and` resilient. To hold the Wood sections and these cushionblocks in place, binding-hoops 17 are provided. These binding-hoops at points preferably equidistant are provided with a tension-spring attachment 18 and a turnbuckle attachment 19, which are illustrated in an enlarged detail in Figs. 4 and 5, which permit the hoops to be drawn up tightly upon the wood sections and at the same time permit of a yielding motion between the different sections. As shown in Fig. 4, the turnbuckle attachment consists of the link 19, throu h one vend of which the end of the rod of t e binding-hoop 17 passes in threaded contact and through the other end of the link the end of the rod of the binding-hoop swivels. As shown in Fig. 5, the spring-tension attachment consists ofthe link 18, through the ends of which the'rod of the binding-hoop swivels, and on one end of the rod intermediate the head 17 and the end of the link is a spring 18', which ives a yielding or sprin tension on the bin ing-hoop when the turn uckle is screwed up. To the sides of these wood sections are secured metallic plates 20, which extend downwardly, so as to overlap the elly and to kee out the dirt from4 the space between the fe ly and wood section when the neumatic tire is fully inflated, as shown in ig. 2. In the top of the wood sections and also in the top of the rubber cushionblocks are grooves 21, in which are received the solid rubber facing-rin 22. Other wearin material ma be substltuted for rubber. 'Fhe bottom o these grooves are small and narrow for the reception of the bindinghoops, as best shown in Figs. 2 and 3. The facing-rings are provided with the usual central strengthening-wire 23.

In assembling the parts of the tire the pneumatic tube is deflated, and after the parts are put into their a pro riate places and the proper tension iro ucc in the binding-hoops it is inflat thereby giving the outer part of the tire its necessary stiffness and resiliency.

By this construction it will be seen that I tire of great durability and Whic will not skid on the ground as .easily as the ordinary autowheel. v It will also be observed that the Wear of the Wheel comes principally upon the facing-rin s, which when worn out can be easily rep aced with little expense compared to the re lacing .of the tires of the ordinary autowhee s.

Having described my invention, what I claim as new, and desire to secure by Letters atent,.isv i l. A vehicle-Wheel rim composed -of a :felly having a channel in its .outer fave; a plurality of sections comI osed of nonnncturable ma- `terial having c annels in i ieir inner faces which together with the channel .in the felly form a pneumatic-tube channel; la .ncumatic tube in said channel; meansto hol said nonpuncturable .sections against separation from Ithe felly; resilient' cushions between the ends of said sections; and Wearing material .exterior said sections and cushions.

2. A vehicle-'wheel rim composed of .a felly having a channel-,infits outer face; a plurality of pins projecting upwardly from the outer .face of saidiell said pins being secured thereto; a plurality of wood sections .havng socketsn their lower facesfor the rece tion of said pins and having channels in said aces, which with the channel in the felly form a pneumatic-tube channel; a neumatic tube msaid tube-channel; conica -sha ed .rubber cushions intermediate said Woo sections; side :plates secured tosaid wood sections and extending downwardly to overla the felly; facing-rings on the outer 4side o said wood sections, said yfacing-rings 'being `received in grooves in said wood sectioisis and .cushions and binding-hoops surrounding saidcushions and wood sections-and received izrgrooves therein. *y l f' In witness that thev foregoing I have 'hereunto subscribed my name this .28th day .of November, 1905,
